It clips directly onto the contactor terminals — no extra wiring, no DIN-rail space consumed. Rated for 400 to 600 V AC at both 50 and 60 Hz, it handles the coil suppression on motor starters and other inductive loads in the panel.
Fit and mounting — no surprises
Clip-on fastening means it snaps onto the contactor's coil terminals without tools. The dimensions are compact: 12 mm deep, 30 mm wide, 19 mm high, so it adds negligible depth to the S0 contactor footprint. For a panel-builder packing multiple contactors side-by-side, this suppressor stays within the contactor's own envelope.
